Guizhou is a mountainous province, although its higher altitudes are in the west and centre. It lies at the eastern end of the Yungui Plateau.^[13]
Guizhou has a subtropical humid climate. There are few seasonal changes. Its annual average temperature is roughly 10 to 20 °C, with January temperatures ranging from 1 to 10 °C and July temperatures ranging from 17 to 28 °C.^{[citation needed]}
Like in China's other southwest provinces, rural areas of Guizhou suffered severe drought during spring 2010. One of China's poorest provinces, Guizhou is experiencing serious environmental problems, such as desertification and persistent water shortages. On 3–5 April 2010, China's Premier Wen Jiabao went on a three-day inspection tour in the southwest drought-affected province of Guizhou, where he met villagers and called on agricultural scientists to develop drought-resistant technologies for the area.^[14]
